Title: Production of polysulfone resin semipermeable membrane
Inventor: SHIMAGAKI MASAAKI
IPC: B01D71/68
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a membrane whose water-permeability and fractional molecular weight can be made to be a wide range and in which choking and staining hardly occur by using a solution in which a polysulfone resin and a hydrophilic polymer and mixed and dissolved as a film forming dope and thermally cross-linking the formed film. SOLUTION: As for a polysulfone resin having formula I and II as a composition component of a film forming dope, any range of the concentration is acceptable if it is sufficient to form a film and given proper characteristics to the film. However, due to the necessity to cover the decrease the polymer concentration to obtain high water-permeability and high fractional molecular weight, it is preferably that the concentration of the polysulfone resin is about 5-20%. It is proper that the addition amount of polyvinylpyrrolidone as a hydrophilic polymer is 3-10wt.%, through it also depends on the molecular weight. In the case that these two polymers are mixed and dissolved in a solvent and then water is added as an additive, the addition amount of water should be about 1-5wt.% since coagulation property of the polysulfone resin is high.  The addition amount of the hydrophilic polymer may be lessened by adding the fourth component.
